basically do whatever you want with this code.
|
|
|
|
u-blox changed how to configure their modules in 2019. As of version 23 of the UBX protocol the
|
|
UBX-CFG commands are deprecated; they still work, they just recommend using VALSET, VALGET, and VALDEL
|
|
commands instead. This example shows how to use this new command structure.
|
|
|
|
Feel like supporting open source hardware?
|

Buy a board from SparkFun!

Hardware Connections:
|
|
Plug a Qwiic cable into the GPS and a RedBoard Qwiic or BlackBoard
|
|
If you don't have a platform with a Qwiic connection use the SparkFun Qwiic Breadboard Jumper (https://www.sparkfun.com/products/14425)

Open the serial monitor at 115200 baud to see the output
